ThruFlow Interlocking Panels are the ideal choice for decks, docks,
walkways, in the home and around pools and spas. ThruFlow is a unique polymer panel that allows water; debris
and sunlight to pass through your walking surface, keeping your walking
surface clean. Sunlight and water penetration in concert helps to keep
vegetation alive, helping to minimize the effect of your walking surface
on the environment.

Now there’s a new way to increase the usable space in your
home with the ThruFlow™ system. Ventilated panels keep air
flowing while allowing you to walk freely throughout your attic and
increase storage space.

Sea Foam Light Grey Maple

Are ThruFlow™ Interlocking
Panels made of recycled materials?

ThruFlow is made from virgin plastic reinforced with fibreglass and
contains no recycled materials. The
use of premium virgin plastic allows ThruFlow™ to offer increased
load bearing and flexural stiffness properties. This allows ThruFlow™
to be used on 16” centers, like most existing structures, without
the need for further support. ThruFlow is recyclable (subject to
local regulations).

What sizes do ThruFlow™
Interlocking Panels come in?

ThruFlow is currently offered in three sizes; Three Foot Panels (12" x
36"), Four
Foot Panels (12" x 48") and Five Foot Panels (12" x 60").

The three-foot panels are meant to cover approximately
36 inches in length and 12 inches in width with a product thickness of
approximately 1.25 inches.

The four-foot panels are meant to cover approximately
48 inches in length and 12 inches in width with a product thickness of
approximately 1.25 inches.

The five-foot panels are meant to cover approximately
60 inches in length and 12 inches in width with a product thickness of
approximately 1.25 inches.

Will the color of ThruFlow™
change?

ThruFlow™ panels should not change color significantly (more than
15% from new) over the first 7 years of exposure.

Do ThruFlow™ Interlocking
Panels come with a warranty?

Yes, ThruFlow™ has a limited warranty. The ThruFlow™ limited
warranty offers coverage against material defects in workmanship and materials,
and against rot, decay and termite damage. The total
life expectancy for ThruFlow™ interlocking panels is currently undetermined.
Accelerated age testing is ongoing and to date we know of no environmental
factors that harm or cause significant deterioration to ThruFlow™.

What types of fasteners are recommended
for ThruFlow™ Interlocking Panels?

We recommend high quality screws such as #10 or #12 pan head stainless steel
screw to take advantage of ThruFlow’s™ longevity. Pre-drilling
is not required as the holes are molded in with a countersink for your
convenience, screws should be clear through the panel and fastened into
the material of your structural frame. Remember not to tighten the screw
down to allow for expansion or contraction.

Are ThruFlow™ Interlocking
Panels structural?

No. While ThruFlow™ is tough and durable, it does not have the same
stiffness as wood. Therefore, it is not intended for use as a load-bearing
structural member.

What joist spans should I use for
my dock, deck or walkway when using ThruFlow™?

For ThruFlow™ panels, the joist spacing should be 16" on center for all
applications (18” for 3’ Product, 15" for 5' Product), which is the same span generally
recommended for wood. Special applications/loading conditions will require
engineering analysis and/or reduced spans, please consult and adhere to your
local building code.

Do ThruFlow™ Panels require
gapping between panels?

Yes, in both directions. While ThruFlow™ Interlocking Panels will not
shrink or swell due to changes in moisture, changes in temperature will
cause slight expansion/contraction. Therefore, gapping is required both
side-to-side and at the panel ends to allow for thermal
expansion/contraction. Rules of Thumb: ThruFlow Interlocking Panels should
be allowed to grow minimum of 1/16" in total length (1/32” each end)
and 1/32” in total width (1/64” per side) for every 30°F of difference
between installation temperature and the hottest temperature expected.

Can ThruFlow™ be painted
or stained?

It is not recommended to paint or stain ThruFlow™. Stain will not
penetrate well and paint will not adhere well to the panel.

Does ThruFlow™ provide good
traction?

ThruFlow’s™ entire walking surface has a knurled finish for slip
resistance and has been tested to provide a 0.78 static coefficient of
friction.

Can ThruFlow™ be used in
full ground contact? Is treating required?ThruFlow™ is ideal for ground contact applications such as walkways
and in-ground pool surrounds. ThruFlow™ is resistant to rot and
insects, and absolutely no treating is required.
